"We see this technology as taking us into the next generation of crime
investigation. For me it's a 'wow factor' to have assistance from a
satellite in space rather than using a spade on the ground. This is
moving forward." "The satellite was sensitive enough to pick up a rabbit hole under
bushes, and the disturbance caused by shotgun shells used in clay pigeon
shooting."

"People for so long, for so many generations, thought that privacy was just a given. 'Well I'm born, I'm a human, I don't see anyone around me so I have privacy. And don't come into my home without a warrant, because I have privacy'. Well, those days are so gone that it's not even funny. They have a van that drives down the street that can look inside your house. They have TV's that monitor the conversation you are having in your living room."

(CNN)-- Months after the murder of Rania Alayed,
the search for her body had ground to a halt. Although her husband --
who had admitted to her killing -- indicated the approximate location
where he buried the body off a highway near Manchester, northern
England, police were still left with miles of open field to dig through.

Frustrated with the high cost and lack of progress, investigators turned to an experimental form of satellite imaging.

"We had been using aerial
photography, and the opportunity came up to look at a larger expanse,"
said detective superintendent Peter Marsh, of Greater Manchester Police.
"It allowed us to identify anomalies on the ground, which we could
search straight away."

The satellite was
sensitive enough to pick up a rabbit hole under bushes, and the
disturbance caused by shotgun shells used in clay pigeon shooting. By
systematically eliminating possible sites of the grave, police say their
eye in the sky has saved them months of fruitless work. The search for
Alayed's body is ongoing, but Marsh believes a significant breakthrough
has been made.

"We see this technology
as taking us into the next generation of crime investigation. For me
it's a 'wow factor' to have assistance from a satellite in space rather
than using a spade on the ground. This is moving forward."

Satellites have been used in criminal investigations before. The Australian authorities
have used them for over a decade in cases of illegal logging, for
example. But technology advances are now enabling far more accurate and
reliable imagery that could revolutionize 21st-century policing,
transforming law enforcement capacity through highly detailed
surveillance.

"Even five years ago the
pixel resolution was one meter at best, with most sensors in the two to
five-meter range," says Dr. Richard Hilton, senior Earth observation
specialist at Satellite Applications Catapult,
the British company that supplied their technology to the Alayed case.
"This year we have 30cm resolution, which dramatically changes the
potential for detecting things, or monitoring a site of interest."

The Alayed case is one of
several pilot schemes the company is running with police forces and
security agencies. A key focus is on organized crime, trafficking and
smuggling. The satellites have been put to work on the illegal fishing
industry, worth up to $23 billion a year, tracking ships to witness crimes in real time.

"We can identify a
specific ship and monitor its behaviour from port to port. We can see if
it meets another vessel in a strange way and offloads cargo, or fishes
in water it's not allowed to," says Hilton.

In addition to improved
resolution, SA Catapult is benefiting from a steady increase in the
number of Earth observation satellites, with launches set to double over the next decade,
making more data available as well as bringing down the cost. This
progress is also enabling the growth of rivals such as U.S. firm Digital Globe, while the Asian market is also expanding.

Some experts believe
space surveillance could become industry standard. "The technologies
that Catapult is developing will have broad application not only for
national and international police organizations but also for anyone
working in international security," said Patricia Lewis, research
director of International Security at think tank Chatham House. Drug trafficking and arms reduction treaties are among the priority applications, says Lewis.

It will soon be cost
effective for police forces to buy their own satellites, predicts Ray
Purdy, expert on satellites and the law at University College London.
Purdy has been able to monitor criminal activity -- such as large-scale
illegal waste disposal -- through satellite surveillance, which would
have allowed police to cheaply and easily strengthen existing cases.

"I've gone back and
looked at crimes after a prosecution and in some cases you can see
illegal activity a year before, which could have allowed a greater
conviction," he said. "In other cases we found people resumed criminal
activity immediately after they were prosecuted."

However, whether satellite pictures are legally admissible remains unclear, as it requires expert interpretation, and has been stricken from the record in some previous cases.

But as resolution
steadily improves toward the point of being able to identify
individuals, the industry will face ethical challenges over privacy.
Purdy, who is preparing a research paper on the subject, says he is
concerned.

"Most satellites are
commercially owned, so if you have money you can buy that imagery. It
means anyone can spy on anyone ...The big thing is this development has
happened without any debate on privacy and once the technology is out of
the bottle it's hard to go back."

Purdy wants to see a
full public consultation and a set of standards established for the use
of satellites in criminal cases, so that they are not introduced by
stealth. But despite the questions that remain unanswered, the age of
satellite crime fighting has already arrived.
